TRACTOR-CULTIVATOR COMBINATION.

Application led May 25, 1922.

This invention relates to a tractor and cultivator combination.'

One object of the invention is to provide Simple, reliable and efficient means whereby a vtool carrying frame may be quickly attached to and detached from a tractor.

Another object is to provide a tractor Aand `cultivator combination in whichfthe' tools may be arranged in a plurality of different groups and for meeting different cultivating requirements Another object is to provide simple and eicient means whereby the control parts of the cultivator maybe simply and quickly adjusted for accommodating the operator.

4These and other objects are accomplished by means of the arrangement disclosed on the vaccompanying sheets of drawings, in which#u f Figurel( is a fragmentary side elevation of ay tractor and cultivator combination embodying myv invention;

A Figure-2 .is a top plan view of the same arrangement; yand Figure 3 is av fragmentary sectional View taken in the plane of line 3--3 of Figure 1.

Figure 4 isa sectional view taken alon line4-4 of rFigure 3. `L vThe various novel features of the invention will be apparent from the following description and drawings, and will be particularly pointed out in the appended claims.

Referring to the figures of the drawings, .it will be noted that the invention is illustratedfinconnection with a tractor including a 4main frame -10 upon which a propelfling; motor 11 mounted and which frame is supported by ground engaging propelling .wheels 12 operably connected to the engine ll-through any Suitable power transmission mechanism.

The main frame includes a plurality of longitudinally extending members 13 and 14 to which frame control handle bars 15 are flexibly connectetd. The bars 15 at their lower yends are pivotally connected at 16 to the rear ends of the fra-me members 13 whereby said handle bars 15 may be given a vertical pivotal movement. Such handle bars 15 are provided with elongated slots v17 and the vrear ends of frame members 14 are provided with elongatedslots 18 through whichbolts 19 pass. By referring partic- .ularlyy towFigure 1 of the drawings, it will Serial No. 563,489.

be noted that by loosening the nuts on the bolts 19 the height of the control handle bars 15 may be varied to accommodate the operator, and when the adjustment is made` the nuts on the bolts 19 maybe tightened forholding the parts in adjusted position. Preferably, loosely and pivotally connected to the main frame at 2O inl advance of the propelling wheels 12 are rearwardly extend-H ing members 21 which are connected at 22 to an arch member 23, Vwhich arch member holds the bars 21 in spaced relationship.

One of the bars 21 continues rearwardly and terminates in acont-rol handle 24 by? arch 23 is a looped member 26 which extends forwardly from the arch and receives the bolt 19 to maintain the relative vertical positions of the main frame and the arch member 23 to which the cultivator tool carrying frame to be referred to later, is attached.

The cultivator attachment includes two main bars 27 at opposite sides thereof, one portion of each of which extends longitudinally and at the inner side and to theirear" of an associated ground engaging depth control wheel 28, the front portion of each bar being looped around in front ofthe associated wheel and then extending rearwardlyV to thev outer side thereof.y Each main bar 27 is secured to a loop shaped bracket 29, theinner portion of which is secured at 30 to an arch member 31 which acts as a spacer between' such brackets and forms a portion of means whereby the cultivator may be quickly attached to and detached from the tractor in a manner to be described hereinafter. Secured to the front end of each of the brackets 29 isa tool holding standard 32 preferably for the reception of hoes which should extend outwardly from said standards to points directly'in front ofthe associated wheels 28 for cutting away any weeds. Secured to the rear end of the loop portion of the main tool carryframe member, forked portions on said frame member, a latch carried by the frame member, a detachable frame, means carried by the detachable frame adapted to engage the forked portions of the mainframe, and a member forming part-.of the detachable frame and` adapted to be secured to the main framejby said latch. y y

3. In Combination, a tractor, having a main frame member, .a detachableV frame, interengaging latching means carried by the main and detachable frames, and interengaging means on the two frames adapted to permit a pivoted movement between the frames to bring the latching means together.

4. In combination, a tractor` having a main frame member, a detachable frame, interengaging latching means carried by the main and detachable frames, interengaging means on the two frames adapted to permit a pivoted movement between the frames to bring the latching means together, guide means adapted to guide the pivoting interengaging means together, and guide means adapted to guide the latehing ymeans together.
